US Water UV Light Introduction
USWATER5.0 & USWATER6.0 Lamp Countdown Reset Sequence
After changing the lamp on the USWATER5.0 & USWATER.0 systems, the controller must be reset in
order for the system to begin its countdown function on the newly installed lamp. To perform this
reset, you must firmly depress the button on the front of the controller and then manually plug the
power cord back into the wall outlet initiating power to the unit. Keep holding down the button for five sec-
onds until you hear an audible chirp indicating the controller has reset the internal timer.
Release the switch and the lamp countdown feature has now been reset. The following two screens will be
displayed during this process.
USWATER5.0 & USWATER6.0 Failure Modes
The US Water Systems controller continuously monitors your UV system and if there is a problem with the
system the controller will provide both a visual and audible signal indicating the specific fault that may be
adversely affecting the operation of your system. The fault conditions are listed in a priority sequence as
follows:
LAMP FAILURE:
If at any time during the operation of the
system, the UV lamp fails to be illuminated, the controller will
return both an audible and visual signal indicating lamp failure. In
addition, a constant audible buzzer will sound during lamp failure.
UV SENSOR FAILURE:
Assuming the system has a UV Sensor
installed, if at any time during the operation of the system, a UV
sensor fails, the controller will return both an audible and visual
signal indicating sensor failure. For sensor failure, the controller
will cycle between "sensor failure" and "water may be unsafe for con-
sumption" screens as an added precaution. In addition, a con-
stant audible buzzer will sound during sensor failure.
